Surely the laser is reading the track its playing, so how it can it also be reading another to copy the data?

Any ideas anyone
Easy. The copy happens on a time-available basis. The higher priority read operation read ahead and buffers music that hasn't been played yet. It's much like those sax players who can do "continuous breathing"...holding a long note while taking air in at the same time.
